This astrolabe is guaranteed to be an authentic antique. The purple pouch as seen in the photos come with the instrument. Historically, each Bedouin Tribe Master had one of these astrolabes to help him navigate either on land (at night) or in water. The tribe master looked up at the stars for the big dipper. After finding the big dipper, he followed the handle which pointed to the north star.Having found the north star, he then knew which way was north. He always used the instrument at night because it was too hot during the day, and the big dipper and the north star was not visible during daylight hours. The Persian Astrolabe is a historical astronomical instrument used by classical astronomers and astrologers. Brass astrolabes were developed in much of the eastern world, chiefly as an aid to navigation and as a way of finding the qibla, the direction of Mecca. In the Islamic world, astrolabes were used to find the times of sunrise and the rising of fixed stars, to help schedule morning prayers.
It was the chief navigational instrument until the invention of the compass and sextant. Its many uses included locating and predicting the positions of the sun, moon, planets and stars; determining local time given the local longitude and vice-versa; surveying, and triangulation.Astrologers of European nations used astrolabes to construct horoscopes. In the Islamic world, they are and were used primarily for astronomical studies, though astrology was often involved there as well. The astrolabe was introduced to the Islamic world the mid-eighth century. The astrolabe was fully developed during the early centuries of Islam. Arab treatises on the astrolabe were published in the ninth century and indicate a long familiarity with the instrument (the oldest existing instruments are Arabic from the tenth century, and there are nearly 40 instruments from the 11th and 12th centuries). The astrolabe was inherently valuable in Islam because of its ability to determine the astronomically defined prayer times and as an aid in finding the direction to Mecca (the qibla). It must also be noted that astrology was a deeply imbedded element of early Islamic culture and astrology was one of the principle uses of the astrolabe.
Many old astrolabes had astrological features that would allow the user to determine horoscopes. Creating a horoscope requires knowledge of the positions of the planets and the ecliptic for a certain date and time. The astrologer interprets the aspects to advise his client. The astrolabe was a convenient way to determine a horoscope because much astrological stress was placed on the position of the ecliptic.
Of particular interest were the ecliptic degree on the eastern horizon (the ascendant), the ecliptic degree on the western horizon (the descendent) and the ecliptic degree on the meridian (the degree of mid-heaven). In use, the astrolabe is set to the time and date of interest birth, death, coronation, etc. And the ecliptic degrees are read directly.The astrolabe could be used to find the "house" occupied by a planet, but an ephemeris was required to find the planetary coordinates for a date.
